SHAVE-REGISTERING DEVICE.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed December 21, 1906x Serial No. 348,946.

To all whom it 711 (1g concern:

.Be it known that I, HUGH O. KELLEY, a citizen of the United States, residing at Sonora, in the county of Sutton and State 01' Texas, have invented a new and useful Shave-Registering Device, of which the iollowingis a specification.

This invention relates to shave registering devices of that. type which depend for their operation upon the relative changes in position 01' the back and other parts of bar-hens chair during the adjustment of the chair to and lrom an inclined position for shaving the occupant.

The invention has for one of its objects to provide a device ol' this character which is 01' simple and durable construction, comparatively inexpensive and easy to manufacture and thoroughly reliable and efficient in use.

A further object of the invention is the provision of a registering device mounted in the back of the chair and operated by a resilient rod attached at one end to one of the arms oi the chair and movable at its opposite end in a slot provided in the back to move into and out of operative relation with the said device, thereby indicating the movements 01' the parts of the chair every time a person is shaved.

With these obj ccts in view, and others, as will appear as the nature of the invention is better understood, the invention comprises the various novel features of construction and arrangement 01 parts, which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

1n the accompanying drawing, which illustrates one oi the embodiments of the invention, Figure 1 is a perspective view ot a portion of a barbers chair showing the registering apparatus applied thereto. Fig. 2 is a i'ragmentary rear view of the back of the chair partly broken away to show details of construction. Fig. 3 is a similar view showing a modified form of device. Fig. 4 is a detail view 01' the resilient actuating rod shown in Figs. 1 and 2. Fig. 5 is a side view of a barbers chair showing a modified term of registering device applied thereto. Fig. 6 is a detail view of a portion of the registering device.

Corresponding parts in the several figures are indicated throughout by similar characters oi reference.

ltel'erring to the drawing, 1 designates the back of a chair suitably hinged to the upper ends of the legs 2 so as to freely swing from an upright to an inclined position, or vice versa, and 3 are the arms of the chair. These parts may be of any approved construction, since the invention is not necessarily limited to this particular form 01' chair.

Arranged on the back 1, and preferably embedded therein, is the registering device 5 having a dial 6 and a hand 7, both of which are exposed at the rear of the back 1, A. suitable step by step mechanism is employed for actuating the hand and the same preferably comprises a toothed wheel 8, an active pawl 9 and a back acting pawl 10., These parts are supported on the irame 11, which is secured to the side member 12 of the back 1. "he pawl 9 is formed on the inner end of the push rod 13 which is longitudinally movable in the opening 14 of the member 12. The member 12 is provided with a vertically extending slot 15 which is open at its iront and the end of the push rod opposite from the pawl extends normally a suitable distance into the slot. Bearing on the push rod is a leaf spring 16 extending lengthwise oi the slot and anchored therein, and having a normal deflection away from the wall of the slot to which one end is attached, as shown in Fig. 2. By this means, the leaf spring 16 is adapted to be straightened out and pressed against the wall of the slot and thereby impart movement to the push rod 13. The push rod is provided with a helical compression spring 17 which returns it to normal position.

The actuator for the leal spring 16 comprises a resilient rod 18 of suitable stiffness which at one end is provided with a ball 19 confined in the slot 15 so as to have a wiping engagement along the leaf spring. The end of the actuator rod opposite from the ball is secured to the arm 3 adjacent the member 12. At a suitable point intermediate its ends, the rod is turned into a coil 20 o as to increase its flexibility. The arrangement of thes parts is such that when the back 1 of the chair is in an upright position, the ball 19 is at the upper end of the slot 15. As the back of the chair is inclined rearwardl y to the usual shaving position, the ball 19 moves lengthwise oi the slot and engages with the spring 16, so that the push rod is actuated and, through the same, the indicating device, so that hand is advanced another point. After the person in the chair has been shaved, the back is moved upwardly to the position shown in Fig. 1 for the purpose of permitting the barber to dress the hair. The ball 19 is returned to its normal position so as to permit the spring 16 and pawl 9 to move into position i'or further actuation when the back is again inclined. It will thus be seen that the necessary movements of the back of the chair during the shaving oi customers are accurately registered for the convenience of the proprietor.

In the modification shown in Fig. 3, the actuating rod 21 is provided with a laterally extending arm 22 that projects through the slot 23 open at both ends in the sides of the member 24 of the back of the chair. The inner end of this arm engages with a vertically extending combined push rod and pawl 25 of the indicating mechanism, which mechanism is substantially the same as that described in connection with the other figures. In this construction, the arm 22 moves from one end of the slot to the other as the back 1 is swung from an upright to an inclined position, or vice versa, so as to actuate the push rod 25 and cause the registering device to indicate.

Referring to Figs. and 6, 26 represents a barbers chair having a seat 27, back 28, and leg rest 29 of ordinary construction mounted so that the leg rest is swung upwardly as the back 28 is inclined rearwardly, as will be readily understood. The indicating device, designated generally by 30, is embedded in the back 28 and is of substantially the same construction as that described in connection with the other figures. The active pawl 31 of the indicating mechanism is connected with the lever 32 which, in turn, is connected by means of the cord or other flexible element 33 to the leg rest. This cord extends downwardly from thelever 32 in the back 28 and over a pulley 34 on the seat 27, thence under the seat to the leg rest. Included in this flexible element is a helical extension spring 35. By this construction, the active pawl 34 is operated each time the back 28 and leg rest 29 are moved for the purpose of throwing the occupant of the chair into the desired shaving position, draft being produced on the cord 33 as the position of the back and leg rest is changed. After the person is shaved, the movable parts of the chair are returned to their normal position and the pawl 31 is retracted and the spring 35 contracts so that the cord is maintained taut. v

I have described the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, but I desire to have it understood that the device shown is merely illustrative, and that various changes may be made, when desired, as are within the scope of the claims.

What is claimed is:

The combination of a barbers chair comprising a movable back provided with a slot, and arms movable with respect to the back, with a registering device mounted on the back, a push rod for actuating the said device and extending into the slot, a leaf spring in the slot engaging the push rod, a resilient member connected with one of the arms and extending into the slot, and an enlargement on the member arranged to have a wipingengagement with the leaf spring.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

HUGH C. KELLEY.
